Solution

Para resolver este problema, podemos usar trigonometría, específicamente la función coseno, ya que tenemos el lado adyacente y la hipotenusa del triángulo rectángulo formado por la escalera, la pared y el suelo.

  1. Identificamos los datos:

    • La longitud de la escalera (hipotenusa) es 6 metros.
    • La distancia desde el pie de la escalera hasta la pared (lado adyacente) es 3 metros.
  2. Usamos la fórmula del coseno: cos(θ)=lado adyacentehipotenusa \cos(\theta) = \frac{\text{lado adyacente}}{\text{hipotenusa}}

  3. Sustituimos los valores conocidos: cos(θ)=36=0.5 \cos(\theta) = \frac{3}{6} = 0.5

  4. Para encontrar el ángulo θ\theta, usamos la función inversa del coseno (arccos o cos⁻¹): θ=cos1(0.5) \theta = \cos^{-1}(0.5)

  5. Calculamos el valor: θ60 \theta \approx 60^\circ

Por lo tanto, el ángulo que forma la escalera con el suelo es aproximadamente 60 grados.
